Apple's 80% Charging Limit for iPhone: How Much Did It Help After a Year?

[polyphenol]

My iPhone 15 Pro Max is at 90% of battery capacity after 708 cycles. My battery is in phenomenal shape for two years old. The new operating system gives me an opportunity to set my charging level so I upped it to 85%, which should still give me the same level of goodness.

My 15PM is 97% after 180 cycles. Currently set to 80% but did have it on 85% for quite a while.

Having my iPad mini means I am probably using the 15PM a bit less when I am out - but the hotspot is on a lot of the time as my iPad is wifi only.

My launch day 16 PM still reports 100% health even on iOS 26 (used that since B1). I never use optimised charging, never used a charging limit, always charge to 100% overnight while I sleep, and I always charge via MagSafe, the current 25W one.

This iPhone has never been charged with a cable plugged in.

All this optmised battery saving stuff is a waste of time to be honest as it makes sod all difference.

I did not enable it.

My iPhone 15 Pro that I bought day one has 599 cycles and it’s still at 88%.

My launch day iPhone 15 Pro is at 96% battery after 342 cycles. It only started to degrade below 100% when I hit around 280 cycles, so degradation seems to be accelerating.

iPhone 14 Pro - 259 cycles - 96%

I charge by plopping it on a MagSafe charger at 20W overnight. No limit on charging level.

This is an enlightening thread!

That’s insane. I have a iPhone 14 Pro and I have had to replace the battery replaced and I am still experiencing bad battery life on my iPhone 14 Pro. Have I just been unlucky?

I have had to recharge my phone at least once every day - see my post below

Getting the iPhone 17 Pro Max - donno why, but my Day One iPhone 14 Pro has terrible battery life and I had to get its battery replaced and even after replacing the battery, I can only keep it for around 1/2 of the day without need to re-charge it.

That is why I am getting the iPhone 17 PM - hopefully I can keep this thing with me without constantly worrying about recharging it throughout the day.

FYI, here is my battery health on my current iPhone 14 Pro, on which I had the battery replaced at an Apple Store:

The battery was replaced just last year too and it is already down to 86%??!?!

iPhone 13 Pro Max - 191 cycles - 102.9% - Original Battery

Charged via slow USB most of the time and try to keep between 80-30%. Not a real heavy phone user so it's easy to keep in the sweet spot.

iPhone 16 Pro Max, about to be 1YR old. I have the charging limit set to 80%. I use Apple 20W charger. I am Cycle Count: 346 Battery Capacity: 99%

Purchased my 15 PM in April 2024. 97% after 191 cycles. I have it set at 85%.

I turned the charging limit off. It would be fine to have on when I’m home but unacceptable at work. I’m a first responder and work 72 hour shifts. I may not see a charger for more than 24 hours or more ant an time and I do need my phone on duty.
It’s wild that Apple hasn’t incorporated charging limits into Focus modes, which I use for work, home and sleep but what do I know?
Also 15 pro, 209 cycles, 100%, 11 months of use since activation. I do have optimized charging on but this feature has screwed me over at work and I’m tempted to turn it off. We’re not quite where I’d like to be with machine learning.
